Perhaps the biggest surprise from Apple's recent iPhone 5s launch event was the introduction of the device's A7 processor, which essentially enables smartphones to deliver 64-bit computing for the first time.

Apple took the wraps off its new iPhone 5S Tuesday, and as rumored, the latest edition of the iconic smartphone touts Touch ID, a capacitive sensor embedded in the home button that unlocks the device by scanning the user's fingerprint. Touch ID, which boasts 500 ppi resolution and scans in 360 degrees, will enable users to log in more quickly than conventional passcodes, Apple explained.

Apple announced its new iPhone 5S will include a motion sensor that will allow the phone to track users' movements. The company's M7 motion coprocessor will continuously measure motion data using the phone's accelerometer, gyroscope and compass, the company said, and information from the sensor will be available to third-party application developers via the new CoreMotion API (application programming interface).

Oddsmakers and insiders say Apple will introduce two new iPhones--the high-end 5S and the mid-range 5C--during a much-anticipated media event scheduled to start at 10 a.m. PT today. Click here later today for Fierce's complete coverage of the Apple event.
